Semi-automatic and full automatic working system at pcp air rifles

ABSTRACT

Invention relates to a system providing both semi-automatic and full-automatic feature to PCP (pre-charged pneumatic) air rifles. While semi automatic or full automatic feature is provided in PCP (pre-charged pneumatic) air rifles separately, PCP air rifle mentioned in working principle developed by us have both semi automatic and full automatic operation capability.

TECHNICAL FIELD

Invention relates to a system providing both semi-automatic andfull-automatic feature to PCP (pre-charged pneumatic) air rifles. Whilesemi automatic or full automatic feature is provided in PCP (pre-chargedpneumatic) air rifles separately, PCP air rifle mentioned in workingprinciple developed by us have both semi automatic and full automaticoperation capability.

BACKGROUND OF THE INVENTION

PCP air rifles are operated by means of an integrated air tube systemmounted thereon and cocking catch. Air pressure of certain amountscontained in the tube produced in different volumes activates themechanism. Thus PCP air rifle can make effective firing up to 500 meterssubject to pressure and tube volume.

Said PCP air rifles have semi or full automatic operating principle.Semi-automatic rifles can make one firing per each triggering withoutneed for setting after initial setting. With full automatic rifles,firing can continue up to magazine capacity as long as the trigger ispulled without need to set again after initial setting. On the otherhand, vibration occurring with rifles working full automatically maynegatively affect the magazine.

For rifles working on semi automatic working principle, firing can notbe made as long as trigger remains pulled whereas for full automaticrifles trigger must be released serially in order to stop firing afterpulled in order to make one firing.

PURPOSE OF THE INVENTION

PCP air rifles having semi automatic and full automatic workingprinciple are provided with both semi automatic and full automaticworking by means of one single mechanism.

When user uses level lever at semi-automatic setting by means ofmechanical system provided, one single firing is made per one singletrigger pulling upon one single setting for magazine. When user putslevel lever in full automatic position, firing continues as long astrigger is pulled upon one single setting. Thus PCP air rifle isequipped with both semi automatic and full automatic use feature.

On the other hand, a support part is added to fix the magazine in orderto protect magazine against vibration occurring particularly during fullautomatic firing.

This is an invention made to equip PCP air rifles with capability tooperate full automatically with the development made in our rifleshaving semi automatic working principle. One of the main components ofthe invention is the level lever (10) pressed by user to activateshifting from semi automatic to full automatic system or from fullautomatic system to semi automatic system for PCP air rifles. Mechanicaloperation structure changes with level lever (10) and thus PCP air riflegains feature of both semi automatic and full automatic operationfeature.

When the level lever (10) shown in FIG. 11 is in semi automatic position(FIG. 5), trigger tab stopper (11) part in upside down T form does notmake any attempt to stop trigger tab (7) thanks to stopper spring (9).When rifle is fired, cock goes forward and then comes back and triggertab (7) moves back and goes in front of semi automatic sheet (12), cock(6) is locked into trigger tab (7) again. Cock (6) is inserted intotrigger tab (7) and motion forward is prevented and re-firing can not bemade. When trigger (13) is released, semi automatic trigger sheet (12)goes above trigger tab (7) and becomes ready for firing. The motions arerepeated and thus semi automatic operation is provided.

When level lever (10) is put in full automatic position, trigger tabstopper (11) part moves upward the connection housing in verticalrectangular form rounded on short edges. Thus trigger tab stopper (11)moves ahead of trigger tab (7). Whenever trigger (13) is pressed, cock(6) is released from trigger tab (7) and initiates firing. Thus triggertab (7) leans on trigger tab stopper (11) part and is not released fromsemi automatic trigger sheet (12) and does not go into position to holdtrigger cock (6). The cock (6) repeats firing motion.

For full automatic firing, the cock (6) is to run in harmony with sheetpusher (2) combining pellet pusher pin (3) and lever wedge (4). Unlesspellet pusher (2) motion is completed, next firing should not be made bythe cock (6). In order to solve this issue, the mechanism (1) is addedfull automatic tab (25) in form of plane without wings, which is shownin FIG. 12 and is one of main factors of our invention.

When the cock (6) returns, full automatic tab pusher shell (17) and fullautomatic tab pusher spring (16) having full automatic tab spring cover(15) goes upward from full automatic tab (25) tail (29) part. Thus fullautomatic tab (25) allowed to move by full automatic tab pusher pin (26)passing through hole in full automatic tab (25) body leaves the balanceposition and goes in front of wedge (27) located on nozzle (28) of fullautomatic tab (25) and thus holds the cock (6). Meanwhile, lever (5)connected onto lever wedge (4) goes back and takes front position andmoves full automatic tab (25) downward from tail (29) and providesrelease of cock (6) wedge (27) from nozzle (28) of full automatic tab(25) and re-firing. This cycle continues synchronously until trigger(13) is re-released.

When cock (6) returns, the wedge (27) located on the cock (6) leans ontofull automatic tab (25) nozzle (28) and holds the cock (6) by means ofthe wedge (27) and prevents front motion of the cock (6). Then the lever(5) connected to pellet pusher (2) by means of lever wedge (4) comesback and moves forward and moves full automatic tab (25) downward fromthe tail (29) and releases the cock (6). This mechanic operationcontinues until trigger (13) is released. Also during this operation,full automatic tab (25) and the parts located around and full automatictab (25) are protected by full automatic tab housing cover (24) andtheir removal is prevented. In addition, trigger case (8) containingtrigger (13), semi automatic trigger sheet (12), trigger tab (7),trigger tab stopper (11) therein is protected by means of closingtrigger case cover (14)

In order to protect magazine against vibration occurring during firing,support part (20) is connected to magazine and lower part of magazine bysupport screw (18) as shown in FIG. 1. Magazine support part tab (19) isconnected to lower part of magazine support part (20) in U shape bymeans of support pin (21). While motion is provided by help of levelspring (22), level feature is provided by means of level ball (23).While magazine housing is empty, magazine support part tab (19) isprotected thanks to foldable towards magazine housing as a result ofsuch motion.
